This stereo pair of images were taken by the rover front cameras on Sol
26. The rover was facing towards the south southeast and was located 5 meters
from the Pathfinder lander. It shows a rock-strewn surface between the rover
and Mermaid "dune." Mermaid, the dark, horizontal area seen betwen
rocks near the horizon, is the target for the next APXS measurement. Some
of the rocks in the very near field show features attributed to wind erosion.
The small rock on the left shows "flutes" (streamlined depressions)
and the slighly larger rock on the right shows features that appear to point
up-wind (wind coming from the left rear of the rover).

The images above comprise a stereo pair taken from the Sojourner rovers'
front cameras on the morning of Sol 42. Visible in the foreground is the
rock nicknamed "Flat Top." Based on previous images from the Pathfinder
lander camera, Flat Top appeared to have a layered texture (in the opinion
of some scientists). These close-up images show that this is probably not
the case. The texture visible on the side of the rock is made up of elongated
pits, which may be either vesicles from volcanic outgassing or etches caused
by weathering. The boundary between the edge and top of the rock exhibits
topography, some of which correlates to the flute-like texture on the top
surface. These depressions may have been carved by the wind, but more study
of Flat Top is needed before this can be confirmed.

Left and right images of the Sojourner rover perched atop Wedge rock
during Sol 47. Sojourner has safely traversed off of Wedge and is now the
vicinity of Shark rock where it will perform additional APXS measurements.
In these images the vantage point of the IMP camera provides a view looking
into the throat of the APXS. The APXS is the round object in the center
of the front surface of the rover.

The Sojourner rover's Alpha Proton X-ray Spectrometer (APXS) is shown
deployed against the rock "Moe" on the afternoon of Sol 64 (September
7). The rocks to the left of Moe are "Shark" (left of Sojourner)
and "Half Dome" (behind Sojourner). They were previously measured
by the APXS.

This stereo image pair shows the Sojourner rover in the middle of
the afternoon on Sol 66 (September 9). The rover has backed away from the
rock "Moe" (to the right of the rover) after measuring its composition
with the Alpha Proton X-Ray spectrometer. The next target for Sojourner,
the rock "Stimpy," is in front of Moe.

This stereo image pair shows the Sojourner rover's Alpha Proton X-ray
Spectrometer (APXS) deployed against the rock "Stimpy" on the
afternoon of Sol 68 (September 11). The two rocks behind the rover were
previously analyzed by the APXS.

This stereo image pair taken on the afternoon of Sol 71 (September
14) shows Sojourner leaving the "Rock Garden," an assemblage of
large rocks behind and to the right of the rover. Sojourner's last target
was the rock "Stimpy," seen at the far right.

This stereo image pair of the rock "Half Dome" was taken
by the Sojourner rover's front cameras on Sol 71 (September 14). Pits, linear
textures, and pronounced topography on the rock are clearly visible.

This stereo image close-up of the rock "Moe" was taken from the
Sojourner rover's front cameras on 70 (September 13). Flute-like textures
on the rock, possibly caused by wind abrasion, are clearly visible.

The rock "Stimpy" is seen in this stereo close-up image pair taken
by the Sojourner rover's front cameras on Sol 70 (September 13). Detailed
texture on the rock, such as pits and flutes, are clearly visible.

This stereo pair image mosaic shows the Sojourner rover near the large rock
"Chimp" on the afternoon of Sol 72 (September 15). Prior to the
acquisition of these images, Sojourner successfully traversed the terrain
between Chimp and the "Rock Garden," an assemblage of large rocks
to the right of this mosaic.

This stereo image pair of the rock "Chimp" was taken by the Sojourner
rover's front cameras on Sol 72 (September 15). Fine-scale texture on Chimp
and other rocks is clearly visible. Wind tails, oriented from lower right
to upper left, are seen next to small pebbles in the foreground. These were
most likely produced by wind action.

These two views of the rock "Chimp" were acquired by the Sojourner
rover's right front camera on Sol 74 (September 17). A large crack, oriented
from lower left to upper right, is visible in the rock. A dark crust appears
to cover Chimp in some areas whereas other parts of the rock have a lighter
shading. A boundary between the two regions is clearly seen in the upper
left part of Chimp.

This stereo image pair shows the Sojourner rover behind the large rock "Chimp"
near noontime on Sol 75 (September 18). The rover's middle right wheel is
raised above the surface. Sojourner is over 12 m from the lander, a mission
record.

This stereo image pair taken by the Sojourner rover's front cameras
was taken on Sol 76. The "Twin Peaks" (~ 1 km away) are seen on
the right horizon, as is "Big Crater" (2.2 km away) at left. This
new viewing perspective shows dunes and rocks not visible from the Pathfinder
lander.

This stereo image pair taken on the morning of Sol 80 (September 23)
shows the Sojourner rover with its Alpha Proton X-ray Spectrometer (APXS)
deployed against the rock "Chimp." On the left horizon is the
rim of "Big Crater," 2.2 km away.
